one-third to Josephv -W. Gomiskey andone- I third to Joseph Siciliano, both of Johnsto Application. November 17, 1931, Serial No. 575,663 Renewed-t October 27, 1934 i In the present invention I provide means. to. permit expeditiousrrepiacement of heels on shoes, the invention being especially adapted for use in interchanging or replacing rubber heels.

Objects of the invention are to provide attaching means through the medium of which rubber or other heels may be attached by persons unskilled in the art to which this invention relates; to provide attaching means which will positively retain the attached heel in snug engagement with the shoe; to provide attaching means which permits the heel to be engaged to or disengaged from the shoe without the use of special instruments; to provide an attaching means for use in detachably engaging a heel tread with a ladys shoe, the attaching means being constructed to prevent rotation of the tread; and to provide an attaching means exceedingly simple in construction, yet durable to withstand the strain imposed thereon.

Other objects of the invention will be apparent from the following description of the present preferred forms of the device, taken in connection with the accompanying drawing, wherein Fig. l is a fragmentary bottom plan view of a shoe, showing an attaching plate, constructed in accordance with my invention, applied thereto;

Fig. 2 is a cross-sectional view taken on the line 2-2 of Fig. 1, looking in the direction of the arrow;

Fig. 3 is a similar View, taken on the line 3-3 of Fig. 1;

Fig. 4 is a detail enlarged fragmentary sectional view of a shoe, heel tread and screw or bolt, said elements being shown separated;

Fig. 5 is a similar view of a modified form of tread; showing the screw in place;

Fig. 6 is a bottom plan view of a ladys heel showing a plate, constructed in accordance with the present invention, attached thereto; and

Fig. 7 is a perspective view of the plate illustrated in Fig. 6.

'In the drawing, in order to illustrate the application of this invention, I have shown a portion of a shoe 8, which is equipped with the usual heel portion 9, in which a recess I 0 is formed, the recess extending completely around the heel portion 9 but appreciably spaced from the perimeter thereof.

In the recess I0 I mount an attaching plate I I, which conforms to the configuration of the recess, the outer face thereof being flush with the outer face of the heel proper 9. The plate may be fixedly secured to the heel 9 by nails I2 or other desirable fastening means. The plate is also provided with a plurality of screw threaded openings Is3 ,.the2 outer end? of each of which is flared asindicated atv I i, toiprovide a bell-shaped: guide for a purposemore fully hereinafter set forth.

I have in the drawing shown two different kinds of heel treads, one of which is shown to advantage at I5, in Fig. 4 and the other of which is shown at IS, in Fig. 5. These treads'may be made of rubber, composition, fiber, or other suitable material. The device of the present invention,'however, is especially adapted for use with rubber heels. In the tread shown in Fig. 4, a plurality of metal discs or washers I! are mounted therein, approximately midway the opposite faces of the heel. Each of the discs or washers I! is provided with a central opening which corresponds with an opening IS in the tread and is adapted to receive therethrough a screw threaded bolt I9, which latter extends through the bell shaped guide It. of the plate I I and into engagement with the screw threads I3. ,It is of course, already well known in the art to employ discs or washers mounted in a rubber heel and consequently, the device of the present invention may be used with standard types of heels. In the form of invention shown in Fig. 5, the tread I5 is made of leather and is equipped with a series of sleeves or bushings 20, one end of each of which latter is bent outwardly, as indicated at 2 I. The tread is provided'with openings 22, each of which is adapted to receive a sleeve or bushing 26, each opening extending completely through the heel. When the sleeve or bushing 20 is in place, the out-turnedportion ZI thereof lies in proximity to the outer surface of the heel, the inner end thereof terminating intermediate the opposite faces of the tread. The sleeve or bushing is preferably of truncated cone shape to permit a screw 23 to be introduced thereinto in a facile manner and to provide a wedge engagement between the screw head and the sleeve when the screw is urged into engagement Withthe plate II.

In Fig. 6 of the drawing, I have shownthe heel 25 of a ladys shoe which has a plate 26 mounted thereon and secured thereto by nails 21 or the like. The plate is adapted to detachably receive, on the outer face thereof, a tread, which latter may be formed of rubber or other suitable material and is maintained from rotation by outturned corners 28, formed on the plate. The corners 28 act as fingers to embrace the tread. The plate 26 has a screw-threaded opening 29 formed therein, which is adapted to receive complemental threads on a screw engaged through a tread mounted on the attaching plate 26.

With the device of the present invention it is apparent that not only may rubber heels and other forms of treads be replaced, but additionally these treads may be expeditiously interchanged. It is well known that heel treads are usually worn down on one side only with the result that it is necessary to discard them, while the major portion of the tread is still usable. With the present invention, the heel may be used until almost completely worn out. It may be quickly attached to and detached from the regular heel portion of the shoe by the use of a screw driver for operating either the bolt I9, or the bolt 23, as the case may be. Notwithstanding the fact that the heel tread can be quickly removed in a facile manner, it is nevertheless likewise apparent that the means employed is effective to positively hold the tread in snug engagement with the shoe heel proper.

Although I have herein described the preferred forms of my invention, it is to be understood that various changes may be made in the construction, proportion and arrangement of parts, within the scope of the appended claim.

What is claimed is:

Means for attaching a heel tread to a shoe, in combination with a relatively narrow apertured plate engageable with the shoe heel in spaced relation to the margin of the latter, a tread mounted on the plate and provided with openings extending therethrough in alignment with the plate apertures, a truncated cone shaped bushing mounted in each of said openings, the outer end of each bushing being flared at the wearing surface of the tread, and a fastening means engaged through each bushing and with an aperture of the shoe plate, the head of the fastening means complementing the bushing to facilitate guiding said means into the plate apertures, the inner end of the bushing being in wedge shape engagement with the head of the 20 fastening means.
